-5x-5y=-25

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Add 5x to both sides of the equation.

-5y=-25+5x

Divide each term by -5 and simplify.

Divide each term in -5y=-25+5x by -5.

-5y-5=-25-5+5x-5

Cancel the common factor of -5.

Cancel the common factor.

-5y-5=-25-5+5x-5

Divide y by 1.

y=-25-5+5x-5

y=-25-5+5x-5

Simplify -25-5+5x-5.

Simplify each term.

Divide -25 by -5.

y=5+5x-5

Cancel the common factor of 5 and -5.

Factor 5 out of 5x.

y=5+5(x)-5

Move the negative one from the denominator of x-1.

y=5-1⋅x

y=5-1⋅x

Rewrite -1⋅x as -x.

y=5-x

y=5-x

Reorder 5 and -x.

y=-x+5

y=-x+5

y=-x+5

y=-x+5

Using the slope-intercept form, the slope is -1.

m=-1
